Changing web service access
You can block and unblock web services for all firewall nodes using a user interface command button.
Note: Only users with fire privilege 1 and higher can access this function.
To allow remote read access:
1. Sign in with fire privilege 1 or higher, and then tap System Info on the Action bar.
2. On the Command bar, tap Unlock Incoming Network. This unblocks web services for all firewall nodes.
To disallow remote read access:
1. Sign in with fire privilege 1 or higher, and then tap System Info on the Action bar.
2. On the Command bar, tap Lock Incoming Network. This blocks web services for all firewall nodes.
Freezing the events history
When the Freeze History command is activated, the system archives the most recent events (up to 10,000) so
that they cannot be overwritten.
Note: Only users with fire privilege 3 can access this function.
To freeze event history:
1. Sign in with fire privilege 3, and then tap System Info on the Action bar.
2. On the Command bar, tap Freeze History.
Changing the smoke detector alarm sensitivity threshold
Intelligent addressable smoke detectors are configured with two alarm sensitivity thresholds: primary and
alternate. The alarm sensitivity setting determines how easily automatic fire detectors can sense a fire alarm
condition.
A time control is commonly used to automatically switch alarm sensitivity thresholds. However, you can manually
switch alarm sensitivity thresholds by using a command button.
Note: Only users with fire privilege 3 can access this function.
Primary alarm sensitivity threshold: Typically, the primary alarm sensitivity threshold is set to a lower
threshold. This threshold is commonly used for a daytime operation to reduce the occurrence of nuisance alarms
when a facility is occupied, or when environmental conditions may create prealarm conditions.
Alternate alarm sensitivity threshold: The alternate alarm sensitivity threshold sets the secondary threshold at
which the smoke detector activates an alarm event. Typically, the alternate threshold is set to a higher sensitivity
threshold. This threshold is commonly used for a nighttime or weekend operation, when the facility is unoccupied.
To activate the alternate alarm sensitivity settings:
1. Sign in with fire privilege 3, and then tap System Info on the Action bar.
2. On the Command bar, tap Toggle Alternate Sensing.
